{Decimals}
Hi, I'm stuck on these problems, and I asked my family members, they don't know, so I've come to you, community! Please help, thanks.
Directions:
Round each decimal to the underlined place-value position.
4.2974
(seven is the underlined number)
39.987
(nine is the underlined number.)
0.085
(zero is the underlined number)
Thanks, just three questions from my homework and hopefully I can manage the rest of it.
4.2974 = 4.297
39.987 = 40.0
0.085 = 0.1
If the number on the right side is lower than 5 then the (underlined) number stays the same and if the number on the right is 5 or higher then the underlined number goes up one
the number on the right side of the underlined number***
Thank you
Hi. I'm in 7th grade too. Look to the right of the underlined number. Determine if it is between 0-4 or 5-9. If it is in the category 0-4 keep the number the same.
If it's in between 5 and 9, round it up to the next number in the number line. EX: 2.15 underlined is 1...you would round it to 2.2 I hope this helps!
To round the decimals to the underlined place-value position, you need to determine the digit in the next place-value position.
1. For 4.2974, the underlined number is 7. To round it to the nearest hundredth place (two decimal places), look at the digit after the underlined number, which is 4. Since 4 is less than 5, you don't need to round up. So, 4.2974 rounded to the nearest hundredth place is 4.30.
2. For 39.987, the underlined number is 9. To round it to the nearest tenth place (one decimal place), look at the digit after the underlined number, which is 8. Since 8 is greater than 5, you need to round up. So, 39.987 rounded to the nearest tenth place is 40.0.
3. For 0.085, the underlined number is 0. To round it to the nearest thousandth place (three decimal places), look at the digit after the underlined number, which is 8. Since 8 is greater than 5, you need to round up. So, 0.085 rounded to the nearest thousandth place is 0.086.
Remember, when rounding decimals, you look at the digit in the place-value position you want to round to and determine whether to round up or leave it as is based on the digit immediately after.
